The second Problem Of The Week has now been posted, along with an official solution to the first problem. Enjoy!

How to catch a speeding star (Synopsis)

“Most people don’t know what’s happening around them because they’re just speeding through life. And before they know it, they’re just old. So I just try to slow it down.” -Tracy Morgan Travel fast enough through the air, and you’ll exceed the speed of sound. The compressed air in front of you builds up, denser…

“What you get by achieving your goals is not as important as what you become by achieving your goals.” -Zig Ziglar What a week it’s been here at Starts With A Bang, where we’ve been proud to bring a number of stories to light for you. This past week, in case you missed anything, we’ve tackled: Is the…

“Go then, there are other worlds than these.” –Stephen King, The Dark Tower When you think about the Multiverse, everyone thinks about the Universe beyond what’s accessible to us. But whether you think about more Universe like our own, multiple Universe that are disconnected from ours, an infinite number of parallel Universes, where possibly multiple…

“Think about it this way – a boomerang goes out and comes back to you if you throw it. If you throw it out at the universe, it will come back down to you on Earth.” -J. B. Smoove Give a planet a kick, and it goes into a more distant orbit around our star.…

“Now the world has gone to bed, Darkness won’t engulf my head, I can see by infrared, How I hate the night.” -Douglas Adams In 1990, the Hubble Space Telescope was launched and deployed, becoming the first space-based observatory. In the years since, many others have followed, covering the entire electromagnetic spectrum, but with nothing…

POTW Returns!

Snow? Bah! Problem Of the Week doesn’t care about snow. That’s right, it’s time for another semester of teasers, enigmas, and conundrums. Our theme this term is: NUMBER THEORY, WITH MATH JOKES As always, we start with a fairly easy problem. Overall, though, I think the problems this term are a little more challenging than…

One of the things about being a physicist that makes it tough to have any sensible work-life balance is that I’m constantly seeing little things and thinking “Oooh! Physics!” then getting distracted from what I’m actually supposed to be doing. Take, for example, our bathroom sink. I have noticed, from time to time, a weird…

“So numerous are the objects which meet our view in the heavens, that we cannot imagine a point of space where some light would not strike the eye;—innumerable stars, thousands of double and multiple systems, clusters in one blaze with their tens of thousands of stars, and the nebulae amazing us by the strangeness of…
